Abstract

The invention relates to the field of lifting and transport machinery, namely, devices for supplying the working fluid from the fixed part of the machine to the turning part. The purpose of the invention is to increase reliability. The pipeline 8 is connected to the insert 10, the concentric grooves 13 of which are connected to the openings 11 of the insert 9 mounted on the shaft 4, inside of which are installed the hydraulic lines. Inserts 9, 10 are spherical and spring loaded. When the shaft 4 rotates, the liquid is supplied through the grooves 13 of the liner 10, the holes 11 of the liner 9 and the hydraulic line 7 of the shaft 4. 1 sludge. with 4 SL

Description

The invention relates to a machine-building lifting industry, namely, devices for supplying a working fluid from a non-rotary part of a machine (preferably a lifting edge) to a rotating part.

The purpose of the invention is to increase reliability.

The drawing shows the proposed device, a General view.

The device for supplying the working fluid from the non-rotating part of the machine to the rotating part contains a well-shaped body 1 mounted on the non-rotating part 2 and made with a lateral hole 3. The shaft 4 is mounted on bearings 5 in the body 1 and is rigidly connected to the rotating part-6. Hydrolines 7 are located inside the shaft 4. The pipelines 8 are mounted on the non-rotary part 2 "The spherical liners 9 and 10 are located in the housing 1, are mated with each other and made

with holes 11. Deposit 9 fixed 25 of the gate part and connected by one

at the end of the shaft 4. The insert 10 is connected to PR5GZHINA 12 and is made on the side of the insert 9 with concentric grooves 13 communicated with the corresponding openings It of the insert 9, Hydroline 7 is connected to the openings 11 of the insert and the working parts. The pipelines 8 are connected to a power source, with openings 11 of the insert 10, and with opening 3 of housing 1.

The device works in the following way.

Fluid is supplied to the ports. 11 inserts 10, enters the concentric grooves 13 of the inserts 10, then through the holes 11 the inserts 9 enters the hydrolines 7 and goes to the working bodies. The waste fluid is recycled. Shaft rotation 4
